Justin received a master’s degree in mechanical engineering from Carleton University. His research focuses on improving ventilation system design and control in existing and new multi-unit residential buildings.
Projects
Assessing and improving ventilation system performance in Canadian multi-unit residential buildings
Assess performance of the centralized pressurized corridor ventilation system vs. decentralized ERV system in two architecturally similar side-by-side high-rise MURBs in Toronto and investigate methods to improve performance through coupled energy and airflow simulations.
